We have a Windows 2003 server where 3 services are running constantly. Sometimes these services consume over 90% CPU. Restarting these services returns normalcy. I need a script/program that will constantly monitor CPU usage and if usage is high then restart those services.

After a bit of research I found this script to monitor CPU usage from Technet.

Script to monitor CPU usage:

(get-counter -Counter "\Processor(_Total)\% Processor Time"
-SampleInterval 1 -MaxSamples 10 |
    select -ExpandProperty countersamples | select -ExpandProperty
cookedvalue | Measure-Object -Average).average

This monitors the CPU usage for 10 seconds and then displays the averaged output.

Also from Stack Overflow and Server Fault I found the scripts to restart Windows services. (Which one is better?)

Now all I need is for the CPU usage script to call the service restart scripts when the condition that usage is >90% is met. Any help would be appreciated.

which services cause the high CPU usage? Use xperf to see which functions cause the usage. – magicandre1981 Apr 1 '13 at 6:01
We run an EPABX application on the server..the services are related to the same...I know the services..I only need a way out to restart them automatically when them automatically when they start hogging resources. – Gh0sT Apr 1 '13 at 9:17
Yeah ... would be great if yo could specify what kind of Operating system are do you need it for. The solution for Linux is really easy - mpstat -A | grep all | head -1 will give you CPU usage and based on its value you could restart the services. In windows i would advise to use powershell Get-WmiObject win32_processor | select LoadPercentage |fl which will give you CPU usage and to restart services use command sc with proper switches/parameters. – mnmnc Apr 1 '13 at 9:46
It's Server 2003. @mnmnc I think that WMI script you worte would show the CPU usage at any particular instant. Now there can be a number of reasons that the CPU usage can suddenly spike. I specifically need a script that will monitor the usage for a period of time (say 10 seconds) then if it's >90%, will restart some specific services. I might add that the services don't stop we need to wait some time/check their status to start them again. Any help would be highly appreciated. Thanks in advance. – Gh0sT Apr 1 '13 at 12:43
you should contact the creator of the tools and ask them why the service hogs the CPU. – magicandre1981 Apr 1 '13 at 18:44

Just for the's the answer:

$cpuutil=(get-counter -Counter "\Processor(_Total)\% Processor Time" -SampleInterval 1 -MaxSamples 5 |
    select -ExpandProperty countersamples | select -ExpandProperty cookedvalue | Measure-Object -Average).average

If ($cpuutil -ge 90)
{Restart-Service MyService1, "My Service2", MyService3}

Powershell truly makes life simpler!

If a commercial solution is OK, check out our Service Protector. It will babysit any windows service and restart it if it hogs the CPU for too long.

As I mentioned already...these are NOT windows services – Gh0sT Apr 1 '13 at 12:58
@gh0sT - I'm confused - you've said that the OS is Win2003 server and now that those are not Windows services. I guess you might mean that the services are not created by Microsoft as in 'not shipped with Operating System' but a third party services running on Windows2003 server. Am I correct? – mnmnc Apr 1 '13 at 13:09
Yes..exactly..these are third party services – Gh0sT Apr 1 '13 at 13:26
